Household and similar electrical appliances - Safety - Part 2-76: Particular requirements for electric fence energizers
IEC 60335-2-76:2018 deals with the safety of electric fence energizers, the rated voltage of which is not more than 250 V and by means of which fence wires in agricultural, domestic or feral animal control fences and security fences may be electrified or monitored. Examples of electric fence energizers coming within the scope of this standard are:
– mains-operated energizers;
– battery-operated electric fence energizers suitable for connection to the mains;
– electric fence energizers operated by non-rechargeable batteries either incorporated or separate.
This standard does not apply to:
– electromagnetically coupled animal trainer collars;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– separate battery chargers (IEC 60335-2-29);
– electric fishing machines (IEC 60335-2-86);
– electric animal-stunning equipment (IEC 60335-2-87);
– appliances for medical purposes (IEC 60601).
This Part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard. This third edition cancels and replaces the second edition published in 2002, Amendment 1:2006 and Amendment 2:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– the text has been aligned with Edition 5.2 of Part 1;
– additional requirements for security fence energizers have been introduced (Clauses 3, 7, 19, 22, Figures and Annex BB);
– specific requirements for battery operated energizers have been moved to Annex S.
The contents of the corrigendum of November 2018 have been included in this copy.
Appareils électrodomestiques et analogues – Sécurité - Partie 2-76: Exigences particulières pour les électrificateurs de clôtures
L'IEC 60335-2-76:2018 traite de la sécurité des électrificateurs de clôtures, dont la tension assignée n'est pas supérieure à 250 V et au moyen desquels des fils de clôtures pour clôtures agricoles, de contrôle des animaux domestiques ou sauvages et clôtures de sécurité peuvent être électrifiés ou commandés.
Les éléments suivant sont des exemples d'électrificateurs de clôtures entrant dans le domaine d'application de la présente norme:
– électrificateurs fonctionnant sur le réseau;
– électrificateurs de clôtures fonctionnant sur piles ou accumulateurs et destinés à être raccordés au réseau (voir la Figure 101 et la Figure 102);
– électrificateurs de clôtures alimentés par piles incorporées ou séparées.
La présente norme ne tient en général pas compte:
– de l'utilisation des appareils par de jeunes enfants ou des personnes handicapées sans surveillance;
– de l'emploi de l'appareil comme jouet par de jeunes enfants.
L'attention est attirée sur le fait que:
– pour les appareils destinés à être utilisés à bord de navires ou d'avions, des exigences supplémentaires peuvent être nécessaires;
– dans de nombreux pays, des exigences supplémentaires sont spécifiées par les organismes nationaux de la santé, par les organismes nationaux responsables de la protection des travailleurs, par les organismes nationaux responsables de l'alimentation en eau et par des organismes similaires.
La présente norme ne s’applique pas:
– aux colliers de dressage pour animaux couplés électromagnétiquement;
– aux appareils destinés à être utilisés dans des locaux présentant des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière, vapeur ou gaz);
– aux chargeurs de batteries séparés (IEC 60335-2-29);
– aux équipements électriques de pêche (IEC 60335-2-86);
– aux appareils électriques d'insensibilisation des animaux (IEC 60335-2-87);
– aux appareils électromédicaux (IEC 60601).
Cette troisième édition annule et remplace la deuxième édition publiée en 2002, son Amendement 1 (2006) et son Amendement 2 (2013). Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques significatives suivantes par rapport à l'édition précédente:
- le texte a été aligné sur celui de l'Édition 5.2 de la Partie 1;
- des exigences supplémentaires relatives aux électrificateurs de clôtures ont été introduites (Article 3, Article 7, Article 19, Article 22, Figures et Annexe BB);
- les exigences spécifiques relatives aux électrificateurs de clôture fonctionnant sur piles ou accumulateurs ont été déplacées vers l'Annexe S.
La présente Partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335-1 et ses amendements. Elle a été établie sur la base de la cinquième édition (2010) de cette norme.

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
